Encouraging motion on Spirit

Posted by Emily Lakdawalla on 2009/11/19 04:54 CST

Results of the first "Free Spirit" extrication drive, sol 2088: not much, as expected

Posted by Emily Lakdawalla on 2009/11/17 03:20 CST

Even though all of us rover fans know that Spirit is really, really stuck, I think I'm not the only one who was secretly hoping that today's images downlinked from Spirit would show that the rover had magically popped out of the ground overnight. Of course, she didn't.

OMG! Aurora!

Posted by Emily Lakdawalla on 2009/10/12 10:43 CDT

Unmannedspaceflight.com member Astro0 was fiddling around with an interesting-looking sequence of Cassini images when he discovered their purpose -- they were gathered in order to see if Cassini could catch aurorae flaring into being near Saturn's north pole. Cassini sure did!

A sunset into the dust

Posted by Emily Lakdawalla on 2009/08/24 12:37 CDT

While Spirit has been stuck at Troy, it's been taking numerous opportunities to capture photos with dramatic twilight lighting. On sol 2,002 (three sols ago, or August 21), it gazed toward the setting Sun, snapping the shutter roughly once a minute.

Triple asteroid 1994 CC rotation animation

Posted by Emily Lakdawalla on 2009/08/06 10:39 CDT

From the "just plain cool" department. I love animations of planetary images and I love radar images of asteroids -- so this animation is doubly cool.

Some beautiful video from the Spirit and Opportunity landing sites

Posted by Emily Lakdawalla on 2008/05/12 06:02 CDT

A majority of the people who work in planetary geology are usually associated with one or maybe two missions, doing all their research on the results from one instrument on one mission. But there are a few people whose expertise cuts across many space missions, and an even smaller number of people who seem to work on almost everything. Randy Kirk is one of those people.
